RESILIENT WHEEL.

inneren.

To all whom t may concern.'

Be it known that we, GASTON CAUvRr and LUC/'inn SALEL, citizens o'l the Republic ot France, and residents of Marseille, France, have invented new and use'liul lmprovernents in Resilient Vv' heels, which iniprovernents are fully set torth in the following specitication.

The present invention has reference to improvements in resilient wheels, and especially ot that type ot' wheel which is equipped with driving teeth that are designed to act on shock-absorbing devices, the improvements in question relating primarily to the construction andv nicainting oi the aforesaid teeth and shock-absorbing devices and being` ot such a character as to result in deadening the shocks due to surtacc irregularities in the road, and in reducing the ett'ects ot these shocks in the part ot the inotor car or other vehicle supported by the axle.

An embodiment otl the invention is illustratcd in the accompanying drawing, whereo't:-

Figure l is a view ot the improved wheel partly in side elevation and partly in longitudinal section; and llig. 2 is a central trans verse section.

As shown in said drawing, the wheel is constituted ot two distinct parts: one lixcd and secured to the hub, and the other inevahle relatively thereto. The first-named part consists ol' a circular disk l which periiendicular to the axis ot the wheel, is inade ot wood, metal or any other suitable inaterial, and is provided at its periphery with .lugs lli, the latter, in the construction illustrated, being substantially Vshaped. These lugs carry cross-pins l5, upon which, in turn, are pivotally mounted the hollow, wedgeor V-shaped 'teeth Q, said teeth serving to drive the movable part oit the wheel and to transmit to it the load ot' the lixed part by means oit` the hercinatteidescribed shock-absorbing devices. rlhe number and size oit the teeth will, ot course, vary in accordance with the dimensions oit' the wheel and the strains to which it is subjected.

The complemental, or niovable part ot the wheel. consists of a circular disk t, whose central portion 5 is recessed, so as to receive the peripheral teeth oit' the fixed disk l. In the thick central portion of the disk Il; is provided. a series oit pairs of recesses t3, the nuniber ot such pairs corresponding to the nurn- Speccation of Letters Patent.

ber. ofY driving teeth, und these recesses, which have an angular arrangement relatively to each other, are designed to receive the alforesaid shock -absorbing devices. Said devices, as will he understood, are also arranged in pairs, one pair acting upon each tooth at opposite sides thereof, and they are constituted ol sliding caps 7 loosely litting in the recesses t3 and containing suitable elastic elements il, here shown as .tornied oi' ilexible washers ot' the so-called Belleville type, though other spring cushioning eleinents inight obviously be used with cipial facility.

(Jn the two tacos ot the disk il are secured cover plates 8 oit nietal or other material, between which cover plates [he hub structure slides. '.l`o cach of these cover plates a` channel ring t) is secured, such ring being adapted to contain packing, tor the purpose ot' preventing escape ot lubricant, 'the inner :laces ol the cover plates e are provided with stops lt), which act to prevent the caps T troni moving entirely out ot their recesses t5, said stops having any size and shape considered expedient, and one olf said cover plates niay be provided with a lubricating plug l5), or a series ot such plugs.

rlhe tire 'l2 is carried by a riin ll which is provided on the periphery ot disk Lt, while the disk l is provided with recesV 13 through which the stay bolts lllpass. Said bolts serve to retain the cover plates S the proper distance apart, and the recesses 12S are oi suitable shape and ot suilicicnt size to perniit the necessary play o't the bolts.

ln order to regulate the tension ot the slioek-abs nbing elements 9,-, there may be arranged in the inner walls ot the recesses a series otl set screws .t7 which niay be adjusted `in the obvious inanner.

le claiinl. A cushion wheel comprising two parts, one ol which carries the hub and has on its circumference radially arranged pivotallyniounted driving teeth ot wedge-shalnd outline and the other ol which is conccnlrit` to the lrst part and is shiltable relatively thereto in the plane thereof, the second part having recesses which extend at angles to one anot her and con'tront the :faces oi the driving teeth, caps slidable in the recesses itoieeiigagenient with'the driving teeth, and shock-absorbing devices arranged in the recesses and engaging the caps.

2. A cushion wheel comprising a relatively fixed hub section and a` ielatively specification in the presence of two subscribmovable rim section, a series of plvotailylng Witnesses. mounted driving niembes of Wedge-shaped outiine borne by the hub section, and L series SC of pairs of shook-absorbing devices borne by the rini section and confronting the faces of Witnesses: the adjacent driving members.
